I have 2.3 but it only works off your current nba live roster. It makes the actual changes to the roster for you. Where as 2.1 was independant and you could use it for any game, which is good for making 2k9 or 2k10 rosters etc. Thanks for your help though.

I ended up finding it in the release topic of 2.3, and luckily the link still worked.
